Abstract

Exemplary embodiments include a tracing clip for a fiber optic cable including: a clip body including an inner and an outer surface; a metal clip disposed on the outer surface; a metal tooth disposed on the inner surface, wherein the metal clip tooth connects to a metal element extending substantially axially along a length of fiber optic cable and to the metal clip.

Claims (24)

1. A tracing clip for a fiber optic cable comprising:

a clip body including an inner and an outer surface;

a metal clip disposed on the outer surface;

wherein the metal clip connects to a metal element extending axially along a length of the fiber optic cable; and

a hinge portion that secures the tracing clip to the fiber optic cable.

2. The tracing clip of claim 1 , wherein the tracing clip has a toroidal shape.

3. The tracing clip of claim 2 , wherein the metal clip connects to the metal element through a metal tooth extending radially inward from the inner surface.

4. The tracing clip of claim 3 , wherein the metal tooth connects to the metal element without disrupting the normal operation of the fiber optic cable.

5. The tracing clip of claim 3 , wherein the metal tooth is capable of penetrating a cover disposed on the exterior of the fiber optic cable.

6. A method of tracing a fiber optic cable comprising:

selecting the fiber optic cable to be traced, wherein the fiber optic cable includes a metal element disposed along a length of the cable;

attaching a first tracing clip to the fiber optic cable, the first tracing clip including a metal clip to form an electrical connection to the metal element; and

applying a tracing signal to the first tracing clip.

7. The method of claim 6 comprising:

attaching a second tracing clip to the fiber optic cable, the second tracing clip including a second metal clip to form an electrical connection to the metal element; and

detecting the presence of the tracing signal at the second tracing clip.

8. The method of claim 7 , wherein a tone generator is used to apply the tracing signal to the first tracing clip.

9. The method of claim 6 comprising:

attaching a plurality of speakers to a plurality of tracing clips disposed on a plurality of fiber optic cables; and

detecting the tracing signal by listening for a tone from one of the speakers.

10. A fiber optic connector for connecting a fiber optic cable to a light source comprising:

a coupling for connection to a fiber optic cable, wherein the fiber optic cable includes a metal element and the coupling includes a means for locking the light source housing to the coupling to connect the fiber optic cable to the light source housing; and

a metal clip connected to the metal element.

11. The fiber optic connector of claim 10 , wherein the metal clip is disposed next to the cage.
